The cooperation between robots and astronauts will become a core element of future space missions. This is accompanied by the demand for suitable input devices. An interface based on electromyography (EMG) represents small, light, wearable device to generate continuous three-dimensional (3D) control signal from voluntarily muscle activation operator's arm. We analyzed influence microgravity tas...

As human beings venture into space in the 21st century, they will be confronted with a "hypodynamic" and thus hostile environment for the bone homeostasis, that could potentially compromise their mobility in general and skeletal strength in particular after landing. From this point of view, space flight studies are especially interesting and intriguing models for scientists. Space studies, howe...

In this article Danny T Quah examines how, when an economy grows, its patterns of production and consumption systematically change. He describes one such large-scale evolution, namely, the increasing weightlessness of aggregate output across advanced economies. In all fast-growing successful countries, growth in information technology has contributed positively both to increasing weightlessness...

The energy metabolism adaptations to simulated weightlessness in rats by hindlimb tail suspension are unknown. 12 male rats were assigned to 7 days of isolation, 7 days of habituation to the suspension device, 10 days of simulated weightlessness, and 3 days of recovery. The 24-hour energy expenditure was measured by continuous indirect calorimetry. We calculated the 12-hour energy expenditure d...

11 With the construction of the international space station Freedom and ongoing preparations for the mission to Mars, man’s presence in space is rapidly increasing. The role of astronauts will become even more important owing to longer and more complex space missions. Since man still remains a central element in the conquest of space despite the outstanding technological achievements, protectio...

Space Motion Sickness (SMS) was reported on the second orbit of the second manned flight. Almost five decades later there is no satisfactory etiology [1]. Virtually all approaches to the problem to date are based on the concept of motions which produce conflicting responses from different sensory modalities. [1,2] Characteristic symptoms are triggered by such sensory conflicts through vestibula...

Bod a K., 1. I II e k, V. S abo: Concentrations o/Mineral Substances in the Tibiotarsus o/the Japanese Quail in Weightlessness. Acta vet. Bmo 1996, 65: 33-37. The concentrations of Ca, P, Mg, and Na were studied in the tibiotarsus of 17-day-old embryos of Japanese quail, in quail 2-4 days of post-embryonic development in the MIR orbital station, and in adult birds of both sexes exposed to 7 day...
